Study Notes

Bite Classification Overview

Class I Malocclusion features proper bite alignment; upper teeth align with lower teeth, but teeth may be crooked, crowded, or turned.
Class II Malocclusion, known as "overbite," occurs when upper teeth extend past lower teeth.
Class III Malocclusion, referred to as "underbite," involves lower teeth protruding beyond upper teeth.

Specific Bite Characteristics

Overbite refers to the vertical overlap of upper teeth over the lower teeth, affecting proper bite function.
Overjet measures the horizontal distance between the upper and lower teeth, indicating how far upper teeth project beyond the lower teeth.
Cross-bite is characterized by some upper teeth fitting inside lower teeth during a bite, potentially leading to alignment issues.
Deep-bite describes an excessive overbite or a closed bite, where upper teeth significantly overlap lower teeth.
